Does this gel contain retinol or strong acids that might irritate sensitive skin?

It is important to clarify that this product does not contain retinol. The "blue retinol" mentioned in relation to the blue-green algae extract (phycocyanin) is a cosmetic comparison referring to its skin-conditioning and antioxidant properties, not an actual retinoid compound. Therefore, it is generally less likely to cause the sensitivity or peeling associated with traditional retinol products.

However, the formula does include papaya extract containing papain, a plant enzyme. Enzymes work by loosening the bond between excess sebum and dead surface cells. While this is typically gentler than physical scrubs or strong acids like glycolic or salicylic acid, it is still an active exfoliating agent. If your skin is very reactive, currently dehydrated, or if you are already using prescription retinoids or strong exfoliating acids in your routine, you should monitor how your skin responds. Over-cleansing or combining multiple exfoliating agents can compromise the skin barrier. Discontinue use if you notice irritation, and consider consulting a dermatologist if you have chronic skin conditions.
